Campaign Finance Database
Updated: May 14, 2013Welcome to Wisconsin’s premier searchable computer database of campaign contributors to candidates for state office in Wisconsin. Regularly updated with financial support from MapLight, this database includes records of contributions of $100 or more from individuals to candidates for the Wisconsin Legislature as well as governor, lieutenant governor, attorney general, state school superintendent and state Supreme Court justices.
The contributor records in this database generally date back to 1993, although in limited cases contributions dating as far back as 1989 are included. State law only requires donors who give more than $100 to disclose their occupation and employer. Please note that, in general, contributions returned by the candidates are excluded from search results.
You have two options when searching for individual contributors. Use the simple search below to search by contributor, employer, city or candidate or use the advanced search to search by more varied criteria.
Contributions from political action committees (PACs) can be found elsewhere on our website.
